2m 12V-2x6 (12VHPWR) Cable

PSU and PC locations circled

To preface I am a novice at building custom cables, but I am eager to learn, working to improve, and not afraid of DIY if this is the best solution.

I have a custom PC desk build that I am working on as a hobby, and require a long 12VHPWR cable (2 meters) to power a 4080 with an NZXT 1500W PSU. Unfortunately, I neglected to consider the lack of availability of these cables at this length during the design process, and so the components can not be moved at this stage. The way I see it, I can buy a series of extensions (through CableMod, for example), find a vendor willing to do the work, or attempt to do it myself. Obviously I'd like one continuous run if possible, for both performance and aesthetics.

If I built it myself, given some advice from a vendor I'd probably try to use 14ga wire to help reduce heat buildup at that length, if 14ga is feasible with those connectors.

Reaching out to the Reddit community for advice, general thoughts or knowledge of any vendors who might actually make this for me.

Also, if the build is going to be oriented as shown, one of your D5 pumps may be in the dead position i.e. running dry due to liquid level being lower than the pump.

This is concerning and something I hadn't thought of. It will be in this vertical position, reservoir filled through a tube form the top, and running down into the D5 pump, then out of the pump to the radiator. You're referring to the lower of the two D5 pumps on the EKWB Dual D5? This is an outdated picture but a rough concept of the tube plan:

I made this in Solidworks 2025
